SH 433 887: Pen-y-Fynwent enclosure, scheduled. <8>
A pentagonal earthwork enclosure defined by a bank and external ditch, with an entrance causeway on the NE. The site has been ploughed heavily, the bank now being less than 1m high and 30m x 30m internally. Probably a pre-medieval homestead, it has been suggested that it is the site of an early chapel, either Bettws Bwchwdw or Capel Tegeryn. <9>
Description Bettws Bwchwdw- site of an early building on an eminence three quarters of a mile south of Parys mountain, towards the western end. (Jones 1855, 26) The site is usually associated with Pen y Fynwent. This is a pentagonal earthwork enclosure defined by a 1m high bank and external ditch c. 30m x 30m internally. (RCAHMW 1937, 146). it may also be the same as Cape! Tegeryn, described as by Trysglwyn (HH No. 12; Baynes 1921, No. 64). Mwchwdw (Machwdo, Bwchwdw) is thought to be the name of a saint (Baring-Gould and Fisher 1911 , iii, 505). They also say a tombstone from the site was used as a door-step to a house in the parish. Discussion The well preserved remains of an enclosure, which may pre-date the chapel and be of prehistoric origin. One (and possibly two) prehistoric tumuli are located in the same field just N of Penyfynwent. Scheduled. The inclusion of the site within the Valor Ecclesiasticus and later lists confirms its status as a church, quite possibly for serving the southern part of the large parish of Amlwch. (Davidson, 2004).
